ILI9341 TFT from Aliexpress- only white screen

Hello!
I bought this display from aliexpress.
I wired it up directly to my Arduino Nano (using 5V logic) and loaded up the graphics test from adafruit library
But the display only shows white screen, and the diagnostics on Serial Monitor shows this (which I assume is not good):

ILI9341 Test!
Display Power Mode: 0x0
MADCTL Mode: 0x0
Pixel Format: 0x0
Image Format: 0x0
Self Diagnostic: 0x0

What am I doing wrong?
This is my setup:

The driver chip requires 3.3V logic. Use a 3.3V Arduino or level converters.

See Step 1 here for ILI9341.
